Nanotechnology has the potential to introduce revolutionary changes to several areas of oil and gas industry such as exploration, production, enhanced oil recovery, and refining. In this paper, the effect of different concentrations of Fe2O3 nanoparticles as a catalyst on the heavy oil viscosity at various temperatures is studied. Furthermore, the effect of a mixture of Fe2O3 nanoparticles and ...

A mathematical model has been developed to predict the temperature distribution in wellbores either offshore or inshore. It is incorporated the different activities encountered during drilling operations. Furthermore, the effect of drill collar and casings and bit rotating in a well during completion has been considered. The two dimensional approach is presented in the form of a computer progra...

This paper discusses parameter-based exploration methods for reinforcement learning. Parameter-based methods perturb parameters of a general function approximator directly, rather than adding noise to the resulting actions. Parameter-based exploration unifies reinforcement learning and black-box optimization, and has several advantages over action perturbation. We review two recent parameter-ex...

Understanding human behavior in the context of exploration and navigation is an important but challenging problem. Such understanding can help in the design of safe structures and spaces that implicitly aid humans during evacuation or other emergency situations. In particular, the role that memory plays in this process is something that is crucial to understand. In this paper, we develop a nove...

This report introduces the grouping-based architecture exploration of the system level design. The grouping-based architecture exploration selects processing elements (PEs) to assemble the system architecture according to the design’s functionality. Furthermore, it maps design’s functional blocks to the selected PEs to pursue the shortest execution time . This report outlines the design flow of...

The aim of this work was to delineate the prospects of podiform-type chromite by staged factor analysis and geochemical mineralization prospectivity index in Balvard area, SE Iran. The stream sediment data and fault density were used as the exploration features for prospectivity modeling in the studied area. In this regard, two continuous fuzzified evidence layers were generated and integrated ...

The UvA Rescue Team will participate in the RoboCup Rescue Simulation League by employing a Simultaneous Planning, Localization and Mapping (SPLAM) approach. This approach augments traditional SLAM approaches with Planning in order to accomplish the set tasks. In this approach SLAM is modeled as one of the potential subgoals that may enable completion of the overall task. The benefit of this ap...
